What is the purpose of the change

Current key ordered lookup join implementation borrows most concepts of FLIP-425 like Epoch, AsynExecutionController, etc. This leads to much code duplication. This pr aims to integrate current implementation into async processing framework which introduced in FLINK-37930. This pr is to replace the implementation in FLINK-37877 while the TableAsyncExecutionController would be removed later.
